Re: apache-karaf in Debian

[Steinar Bang <sb@dod.no>]

Picking up on an old thread.

It would be very nice to get a native debian package of karaf, so I've
opened this RFP:
 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=881297

Karaf is a small OSGi container/applcation server, that has an SSH
daemon, and is provisioned using maven.

Basically, you start the karaf as a daemon, SSH in and meet a command
line that lets you issue commands to pull in applications and their
dependencies using maven.

People familiar with OSGi and the common problems associated with
resolving runtime dependecies will be pleasantly surprised by karaf
features and their resolution mechanism.

Karaf boots from a CLASSPATH containing this set of jars (this is from
karaf 4.1.4) and the rest is pulled in using maven:

Karaf has a concept of "local maven repository" that would fit in nicely
with debian's maven layout under /usr/share/maven-repo/

Modifying the setting org.ops4j.pax.url.mvn.localRepository in
/etc/karaf/org.ops4j.pax.url.mvn.cfg, like this:
 org.ops4j.pax.url.mvn.localRepository = /usr/share/maven-repo
